Cordillera Apolobamba Traverse

The Apolobamba Traverse is a remote, high-altitude backpacking route in the northern Bolivian Andes. Spanning approximately 92km between the villages of Pelechuco and Curva, the trek crosses the ancestral territory of the Kallawaya people—traditional herbalists recognized by UNESCO. The route follows ancient stone paths and animal trails, staying almost exclusively above 4,200m. It traverses several high passes, including the 5,100m Sunchuli Pass, offering direct views of the 6,000m peaks of the northern Apolobamba range. Due to its distance from major cities, it remains one of the least-trafficked and most preserved regions of the Bolivian Andes.

Overview: Son Doong is a massive subterranean karst system with its own weather micro-climates, internal jungles, and underground rivers. Geological Context: Located within the UNESCO-listed Phong Nha-Ke Bang National Park, this limestone giant formed over two to five million years. Booking & Logistics Reality: This is an organized expedition rather than an independent trekking route, requiring authorized guides from Oxalis Adventure and comprehensive logistical support. The 4-day expedition involves a Stage Breakdown across 9km of subterranean passage, requiring hikers to trek through primary jungle and navigate over limestone boulders.
